software development companys like windows, apple and co. produce usable, mostly even good software
but:
- products are getting increasingly expansive and update dependent
- the (end) users loose their independence and individuality

- most of those products can lead to results, but they are not efficent nor powerful –> users are more and more degraded to consumers, than rather beeing their own developers
